RJ6962Battery self-discharge analysis system

In the production test of lithium batteries, self-discharge has always been an important indicator to consider. The traditional test method will test the open circuit voltage (OCV) of the battery, and the K value of the battery can be calculated by observing the change of the open circuit voltage with time. However, this traditional test method needs a long time to stand, so that the open circuit voltage can be sufficiently changed to determine whether the self-discharge capacity of the product is within the allowable range. Due to the large capacity of battery manufacturers, this test method will allow the produced batteries to be stored in the warehouse for a long time, resulting in a lot of funds being occupied by the warehouse. It can be seen that quickly identifying whether self-discharge is qualified has become a top priority for all battery manufacturers.

The RJ6962 Battery self-discharge analysis system can quickly and accurately test the self-discharge current of up to 16 batteries simultaneously for up to 30 minutes.

At the same time, the test mode has two optional modes: approximation mode and normal mode. The test software opens the parameter setting function, and the user can set the initial measurement value, test mode, temperature compensation parameter, and test start and stop according to the actual battery capacity. Higher degrees of freedom, and even low-capacity battery test times can be reduced to about 10 minutes after multiple tests by fixing the starting parameters.
